大豆产量相关性状的遗传定位及候选基因的分析 Title:GeneticMappingandCandidateGeneAnalysisof Yield-RelatedTraitsinSoybean Abstract: Soybean(Glycinemax)isoneofthemostimportantoilseed cropsglobally,providinghigh-qualityproteinandoilinaddition tobeingakeyingredientinvariousindustrialapplications. Understandingthegeneticsunderlyingyield-relatedtraitsin soybeanisofgreatsignificanceforimprovingcropproductivity. Thispaperaimstoexplorethegeneticbasisandidentifypotential candidategenesassociatedwithsoybeanyield-relatedtraits throughgeneticmappingandcandidategeneanalysis. 1.Introduction: Soybeanisaversatilecropwithawiderangeofuses, includingtheproductionoffood,animalfeed,andbiofuel. Increasingsoybeanyieldiscrucialtomeetthegrowingdemands forfoodandagriculturalproducts.Yield-relatedtraits,suchas plantheight,seedweight,podnumber,andyieldperplant,are complextraitscontrolledbymultiplegenesandinfluencedby environmentalfactors.Geneticmappingandcandidategene analysisprovidevaluableinsightsintothegeneticarchitectureof thesetraitsandcanhelpacceleratebreedingprograms. 2.GeneticMappingofYield-RelatedTraits: Geneticmappinginvolvesidentifyingspecificgenomic regionsassociatedwiththeexpressionofatrait.Variousmapping populations,suchasbi-parentalpopulationsandassociation panels,havebeenusedtoperformquantitativetraitloci(QTL) mappinginsoybean.QTLanalysisidentifiesgenomicregions associatedwithyield-relatedtraitsbydetectingsignificant associationsbetweenmarkerlociandphenotypicvariations.This analysiscanelucidatethemajorgeneticfactorscontributingto thesetraitsandallowfortheselectionofsuitablemarkersfor marker-assistedselection(MAS)insoybeanbreeding. 3.CandidateGeneAnalysis: OnceQTLregionsassociatedwithyield-relatedtraitsare identified,candidategeneswithintheseregionscanbe
